mkfifo(1) General Commands Manual mkfifo(1) Name mkfifo - make fifo special files Syntax mkfifo filename ... Description The command creates the `fifo special files' named by its operand list. The operands are taken sequentially, in the order specified, and each `fifo special file' is either completed or, in the case of an error or signal, not created at all. Unless interrupted, will attempt to create all files specified. Error messages are written to standard error. Each `fifo file' is created with a mode of 666, read and write privileges for the user, group and other. The mode is modified by clearing those bits set in the process's file mode creation mask.

mkfifo -- make fifos SYNOPSIS
mkfifo [-m mode] fifo_name ... DESCRIPTION
The mkfifo utility creates the fifos requested, in the order specified. The options are as follows: -m Set the file permission bits of the created fifos to the specified mode, ignoring the umask(2) of the calling process. The mode argument takes any format that can be specified to the chmod(1) command. If a symbolic mode is specified, the op symbols ``+'' (plus) and ``-'' (hyphen) are interpreted relative to an assumed initial mode of ``a=rw'' (read and write permissions for all). If the -m option is not specified, fifos are created with mode 0666 modified by the umask(2) of the calling process. The mkfifo utility requires write permission in the parent directory. DIAGNOSTICS
The mkfifo utility exits 0 on success, and >0 if an error occurs. STANDARDS
The mkfifo utility is expected to be IEEE Std 1003.2 (``POSIX.2'') compliant. SEE ALSO
